This research aims to find the power of three sizes solar panels for suitable of solar water pumps as 360 watts, 350 watts and 350 watts. From the results of comparing the power of the panel. Show that, the highest solar power is type three (350 watts, 2 solar panels) as 800 watts. Because the electric power depends on the receiving area and the light intensity received by the panel.
Most of the agriculture area in Thailand lacks water resources, causing farmers to drill groundwater to use as a source of water for cultivation. In addition, most of the agricultural areas are inaccessible to electrical transmission lines. For this reason, the application of solar water pump is widely interested.
